Ingredients for Lyonnaise Rice Army

Nothing exotic here—just good stuff for French-style comfort on your table.

The onions are the star here. Sweet yellow onions (not red or white) caramelize the best—look for ones that feel heavy for their size at the store. I grab mine at Trader Joe’s or the local farmers market when they’re in season. The rice should be long-grain white (jasmine or basmati work great) for that classic texture. Butter quality matters, so use unsalted so you can control the salt level yourself.

No white wine on hand? Substitute extra chicken stock with a splash of lemon juice—it adds the acidity you need. Out of fresh parsley? Dried parsley at half the amount works in a pinch, but fresh really brightens the dish. For the potatoes, Yukon Golds are a great swap if you can’t find Russets (they hold their shape better too). Skip the pre-shredded cheese if you’re tempted—it doesn’t melt as nicely.

Leftover rice actually gets better overnight as the flavors meld. Store in an airtight container in the fridge for up to 4 days. This also freezes well for up to 3 months—portion into meal-sized containers before freezing. Reheat with a splash of water to keep it from drying out.

Step-by-Step Instructions for Lyonnaise Rice

Here’s how I make this French-style dish with perfect caramelized onions and tender potatoes every time.

Step 1: Caramelize the Yellow Onions

Melt the 0.5 cup Butter in a large, heavy-bottomed pot over medium-low heat. Add all 3 whole Yellow Onions and cook slowly, stirring occasionally, for 30-40 minutes until they turn a deep golden brown.

I resist the urge to turn up the heat—low and slow is the secret here. The onions should melt into a sweet, jammy consistency without burning. Add a pinch of the 1.5 tsp Salt halfway through to help draw out moisture and speed up the process.

Step 2: Sauté the Russet Potatoes

While the onions cook, peel and dice the 2 whole Russet Potatoes. Heat the 2 tbsp Olive Oil in a separate skillet over medium-high heat. Add the potatoes and cook for 8-10 minutes, stirring occasionally, until they develop golden edges.

Season with 0.5 tsp Black Pepper and ½ tsp Salt from the measured amount. The potatoes should be tender but still hold their shape—they’ll finish cooking in the next step. Don’t overcrowd the pan or they’ll steam instead of brown.

Step 3: Deglaze and Combine with Rice

When the onions are deeply caramelized, add the 4 cloves Garlic Cloves and cook for 1 minute until fragrant. Then pour in the 0.5 cup Dry White Wine and scrape up any browned bits from the bottom of the pot.

Let the wine reduce by half, then add the 1.5 cups Rice, sautéed potatoes, 1 whole Bay Leaf, and remaining 1 tsp Salt. Stir everything together so the rice gets coated in all that onion and wine flavor.

Step 4: Cook with Chicken Stock

Pour in the 2.5 cups Chicken Stock and bring to a gentle boil. Reduce heat to low, cover, and simmer for 18-20 minutes until the rice is tender and the liquid is absorbed.

I check at the 15-minute mark—if the rice on top looks dry, I give it a gentle stir and add a splash more stock if needed. The final texture should be creamy, not soupy, with each grain of rice distinct but perfectly cooked.

Step 5: Rest and Garnish

Remove from heat and let sit covered for 5 minutes. This allows the rice to steam and absorb any remaining liquid. Then fluff with a fork and discard the bay leaf.

Garnish with the 0.25 cup Fresh Parsley just before serving. The parsley adds a fresh contrast to the rich, savory flavors. This dish tastes even better the next day as the flavors meld together.

Make-Ahead Tips for Leftovers

Prep Ahead Strategy

You can caramelize the 3 whole Yellow Onions up to 2 days ahead—they keep beautifully in the fridge. Store them in an airtight container with their cooking juices. This saves nearly 40 minutes of active cooking time on meal day. 💡

Potato Prep

Peel and dice the 2 whole Russet Potatoes the night before, then soak them in cold water to prevent browning. In the morning, drain and pat dry before sautéing. This small step makes the morning prep smoother.

Rice Cooking

The rice itself is best cooked fresh, but you can measure and rinse the 1.5 cups Rice the night before. Store it in a bowl of water in the fridge to save 5 minutes of prep time.

Stock and Wine

Have your 2.5 cups Chicken Stock and 0.5 cup Dry White Wine measured and ready to go. If using leftover wine, pour what you need the night before so it’s room temperature when you cook.

Reheating Tips

This dish reheats beautifully. Add 2-3 tbsp water or stock and warm over medium-low heat for 5-7 minutes, stirring occasionally. The flavors deepen overnight, making leftovers a treat. 🔥

Freezing Option

Portion cooled leftovers into airtight freezer bags and freeze for up to 3 months. Thaw overnight in the fridge before reheating with a splash of stock to restore creaminess.
